It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about

X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutations of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems.

FIG. 1A is a perspective view of a hydrant assembly 100 comprising a fire hydrant 110 and a nozzle cap assembly 130, in accordance with one aspect of the present disclosure. The nozzle cap assembly 130 can comprise a nozzle cap 150 and a nozzle cap adapter 160. Example aspects of the fire hydrant 110 can be a wet barrel hydrant, as shown; however, in other aspects, the fire hydrant 110 can be any other type of hydrant known in the art, such as, for example, a dry barrel hydrant. The fire hydrant 110 can comprise a barrel 120 and one or more nozzles 140 (such as nozzles 140 a,b,c). In some aspects, some or all of the nozzles 140 a,b,c can comprise a U.S. Storz nozzles 142 a,b,c. The U.S. Storz nozzles 142 can be non-threaded nozzles that can provide a quarter-turn connection. Furthermore, in some aspects, the nozzle cap adapter 160 can be, for example, a U.S. Storz adapter 162 configured to mount the nozzle cap 150 to a U.S. Storz connector 141 of the U.S. Storz nozzle 142 a. The U.S. Storz connector 141 is shown in further detail in FIG. 1B. In the present aspect, the barrel 120 can be closed at a top barrel end 122 of the barrel 120, as shown. However, other aspects may comprise a hydrant cap or bonnet (not shown) at the top barrel end 122. In a wet barrel hydrant, water can be present and fill the barrel 120 at all times, even when the fire hydrant 110 is not in use. Each of the nozzles 140 a,b,c can house its own independent valve (not shown) to prevent or allow water flow to the respective nozzle 140 a,b,c. In a dry barrel hydrant, the barrel 120 can be drained of water when the fire hydrant 110 is not in use, and a valve for preventing or allowing water flow to the nozzles 140 a,b,c can be housed below ground, such that water will not freeze in the barrel 120 in cold conditions. As shown, example aspects of the barrel 120 can define the top barrel end 122 and a bottom barrel end 124 disposed opposite from the top barrel end 122. Example aspects of the barrel 120 can be substantially tubular and can define a barrel axis 101 extending from the top barrel end 122 to the bottom barrel end 124. In the present aspect, the barrel axis 101 can be substantially vertically aligned.

According to example aspects, the barrel 120 can comprise a base flange 128 disposed at the bottom barrel end 124. The base flange 128 can be fastened to a fluid system (not shown), such as a water main. In one aspect, the base flange 128 can be fastened to a standpipe flange of a standpipe, for example and without limitation. The base flange 128 of the barrel 120 can define a plurality of fastener openings 129 and can be fastened to the fluid system (e.g., to the standpipe flange) by one or more fasteners 127, such as bolt and nut assemblies, engaged with the fastener openings 129. In other aspects, the base flange 128 can be fastened to the standpipe flange by any other suitable connection method known in the art, such as, for example and without limitation, threading, adhesives, welding, any suitable mechanical fasteners, or the like. As shown, example aspects of the barrel 120 can comprise a first operation nut 184 a, or “op nut”, positioned opposite the nozzle 140 a and nozzle cap 150, which can be rotated to open and close a first valve (not shown) mounted in the nozzle 140 a in order to respectively supply or cut off pressurized water flow through the nozzle 140 a from the barrel 120. Example aspects of the barrel 120 can further comprise a second operation nut 184 b positioned opposite the nozzle 140 b, which can be operated to open and close a second valve (not shown) mounted in the nozzle 140 b, and a third operation nut (not shown) positioned opposite the nozzle 140 c, which can be operated to open and close a third valve (not shown) mounted in the nozzle 140 c.

According to example aspects, the nozzle cap 150 can be screwed onto the nozzle 140 a to seal the nozzle 140 a in a sealed orientation. With the nozzle cap 150 sealing the nozzle 140 a, pressurized water from the fluid system cannot escape through the nozzle 140 a. As shown, the nozzle cap 150 can define a cap nut 152 that can be turned, such as with a wrench or another suitable tool, to tighten or loosen the nozzle cap 150 on the nozzle 140 a. Furthermore, in some aspects, a hose cap 170 can be screwed onto the nozzle 140 b to seal the nozzle 140 b in a sealed orientation. Some aspects, such as the present aspect, can further comprise a quick connect adapter 175 attached to the nozzle 140 c for to facilitate the attachment of a fire hose (not shown) to the nozzle 140 c. According to example aspects, the fire hydrant 110 can be formed from a metal material, such as, for example, cast or ductile iron, and some or all of the nozzles 140 a,b,c can be formed from a metal material, such as cast or ductile iron. In other aspects, however, the fire hydrant 110 and/or the nozzles 140 a,b,c can be formed from any other suitable material or combination of materials known in the art.

In example aspects, the nozzle cap 150 can comprise a leak detection system (not shown). For example, the nozzle cap 150 may comprise a vibration sensor, which can be configured to detect leaks within the fluid system by monitoring vibrations travelling up the standpipe and through the fire hydrant 110 when the nozzle cap 150 is mounted on the nozzle 140 a. Vibration patterns within the fluid system can indicate the presence of leaks within the fluid system. According to example aspects, the nozzle cap 150 can further comprise an antenna (not shown), which can be configured to transmit a signal outwards from the nozzle cap 150 to convey whether leaks have been identified within the fluid system.

FIG. 1B illustrates the U.S. Storz connector 141 of the U.S. Storz nozzle 142 a with the nozzle cap assembly 130 (shown in FIG. 1A) removed. As shown, the U.S. Storz connector 141 can generally comprise an outer ring 143 and an inner ring 144 connected to the outer ring 143, and can define a substantially circular shape. The U.S. Storz connector 141 can further define an opening 149 formed through a center thereof in some aspects, and the opening 149 can define a connector axis 103 (extending substantially into the page in the present view). A first arcuate slot 145 a can be defined between the outer and inner rings 143,144. A second arcuate slot 145 b can also be defined between the outer and inner rings 143,144 opposite the first arcuate slot 145 a. The first and second arcuate slots 145 a,b can be substantially concentric to the connector axis 103 in some aspects, as shown. Each of the first and second arcuate slots 145 a,b can define an insertion region 146 and a locking region 147 extending from the insertion region 146, wherein the insertion region 146 can define a width greater than a width of the locking region 147. According to example aspects, the U.S. Storz connector 141 can further comprise a first connector arm 148 a and a second connector arm 148 b, wherein each of the first and second connector arms 148 a,b can extend substantially in the axial direction from a first end 105 of the U.S. Storz connector 141. As shown, the first end 105 of the U.S. Storz connector 141 can be distal to the fire hydrant 110. According to example aspects, the nozzle cap adapter 160 (shown in FIG. 1A), e.g., the U.S. Storz adapter 162 (shown in FIG. 1A), can comprise a pair of nozzle connectors 310 (shown in FIG. 3), wherein each of the nozzle connectors 310 can be configured to engage one of the arcuate slots 145 a,b to couple the nozzle cap assembly 130 (shown in FIG. 1A) to the U.S. Storz nozzle 142 a, as described in further detail below. Furthermore, each of the of the first and second connector arms 148 a,148 b of the U.S. Storz connector 141 can be configured to engage a corresponding ramped surface 403 of the nozzle cap adapter 160 to tighten the nozzle cap assembly 130 with the U.S. Storz nozzle 142 a, as described in further detail below.

FIG. 2 is a rear perspective view of the nozzle cap 150 of FIG. 1A. The nozzle cap 150 can comprise a cap body 210 and a cap cover 280. Example aspects of the cap cover 280 can be formed from a metal material, such as for example, ductile iron, or can be formed from a plastic material, or any other suitable material known in the art. The cap body 210 can comprise an outer housing 230 and an inner housing 340 (shown in FIG. 3). According to example aspects, the outer housing 230 can be substantially cylindrical in shape and can define a first outer housing end 232 and a second outer housing end 234 disposed opposite from the first outer housing end 232. The cap cover 280 can be mounted to the outer housing 230 at the first outer housing end 232, and the inner housing 340 can be mounted to the outer housing 230 at the second outer housing end 234. Furthermore, the outer housing 230 can define a cap axis 201 extending generally through a center thereof, and the cap axis 201 can extend from the first outer housing end 232 to the second outer housing end 234.

According to example aspects, the outer housing 230 and/or the inner housing 340 can be formed from a substantially rigid material. For example, the inner housing 340 can be formed from a metal material, such as, for example, aluminum, and the outer housing 230 can be formed from a plastic material. Example aspects of the plastic material of the outer housing 230 can be a glass-filled plastic material to provide an improved acoustic performance for the leak detection system. In example aspects, the leak detection system can be housed, or primarily housed, in the outer housing 230. In other aspects, each of the inner housing 340 and outer housing 230 can be formed from any other suitable material known in the art.

As shown, in the present aspect, the outer housing 230 can define one or more mounting recesses 236 formed at the second outer housing end 234 thereof, wherein each of the mounting recesses 236 can be configured to receive a corresponding primary mounting leg 442 (shown in FIG. 4A) of the inner housing 340. In some example aspects, a mounting recess hole (not shown) can be formed through each mounting recess 236, and a corresponding cap cover hole (not shown) can be formed through the cap cover 280 and aligned with each of the mounting recess holes. Furthermore, a primary mounting leg hole 544 (shown in FIG. 5) can be formed through each of the primary mounting legs 442. A nozzle cap fastener (not shown), such as, for example and without limitation, a bolt or a screw, can be configured to extend through each corresponding cap cover hole, mounting recess hole, and primary mounting leg hole 544 to couple the cap cover 280, inner housing 340, and outer housing 230 together. In the present aspect, three mounting recesses 236 and three primary mounting legs 442 are present, but other aspects can comprise more or fewer mounting recesses 236 and primary mounting legs 442. Furthermore, according to example aspects, the nozzle cap 150 can be a modular system wherein various components of the nozzle cap 150, such as the outer housing 230, can be easily removed and/or replaced, as desired. For example, it may be desired to remove the outer housing 230 temporarily for repair or to replace the removed outer housing 230 with a new outer housing 230 or a different cap body module. For example, the nozzle cap 150 can be similar to the modular nozzle cap disclosed in U.S. patent application Ser. No. 16/428,744, filed May 31, 2019, which is hereby specifically incorporated by reference herein in its entirety.

FIG. 3 illustrates a rear perspective view of the nozzle cap assembly 130 comprising the nozzle cap 150 and the nozzle cap adapter 160. As shown, the inner housing 340 of the cap body 210 is mounted to the outer housing 230 of the cap body 210. The inner housing 340 can comprise a housing body 342, which can be substantially disc-shaped in the present aspect. Other aspects of the housing body 342 can define any other suitable shape. The housing body 342 can generally define a first housing body end 344 and a second housing body end 345, wherein the primary mounting legs 442 (shown in FIG. 4A) can extend from the first housing body end 344. As such, in some aspects, when the primary mounting legs 442 are received within the mounting recesses 236 (shown in FIG. 2), the first housing body end 344 of the housing body 342 can be configured to abut the outer housing 230 at the second outer housing end 234 thereof. As shown, the nozzle cap adapter 160 can be coupled to the inner housing 340, wherein the nozzle cap adapter 160 can be configured to attach the nozzle cap 150 to the nozzle 140 a. According to example aspects, the inner housing 340 can define an annular outer flange 346 and an annular inner flange 348, each of which can be substantially concentric to the cap axis 201. The annular outer flange 346 and annular inner flange 348 can extend generally axially away from the second housing body end 345 of the housing body 342, relative to the cap axis 201. According to example aspects, an annular gasket groove 460 (shown in FIG. 4A) can be defined between the annular outer flange 346 and the annular inner flange 348, and an annular gasket 350 can be received within the annular gasket groove 460, as shown. In example aspects, the gasket 350 can be configured to abut an end of the nozzle 140 a when the nozzle cap 150 is mounted thereto, in order to create a seal between the nozzle cap 150 and the nozzle 140 a.

Example aspects of the nozzle cap adapter 160 can comprise a first adapter segment 362 and a second adapter segment 364. Each of the first and second adapter segments 362,364 can be substantially semi-cylindrical in shape, such that the first and second adapter segments 362,364 can together define a substantially circular adapter ring 370. The circular adapter ring 370 can define an interior void 372, as shown. The first adapter segment 362 and second adapter segment 364 can be joined together by one or more adapter segment fasteners 365, as described in further detail below with respect to FIG. 4A. In example aspects, the first and second adapter segments 362,364 can be clamped around the outer flange 346 of the inner housing 340 to secure the adapter ring 370 thereto, as is also described in further detail below with respect to FIG. 4A. Example aspects of the nozzle cap adapter 160 can further comprise a latch 380 pivotally coupled to the first adapter segment 362 by a latch fastener 382. In other aspects, the latch 380 can be coupled to the second adapter segment 364. The latch 380 can be configured to engage the nozzle 140 a (shown in FIG. 1A) to lock the nozzle cap assembly 130 onto the nozzle 140, preventing unintentional removable of the nozzle cap assembly 130 from the fire hydrant 110 (shown in FIG. 1A), as is described in further detail below with respect to FIG. 4A. In some example aspects, the latch 380 can be spring-loaded.

According to example aspects, as shown, each of the first and second adapter segments 362,364 can define a first adapter segment end 366 and a second adapter segment end 368. The first adapter segment end 366 of each of the first and second adapter segments 362,364 can be substantially aligned to generally define a first adapter ring end 376 of the adapter ring 370, and the second adapter segment end 368 of each of the first and second adapter segments 362,364 can be substantially aligned to generally define a second adapter ring end 378 of the adapter ring 370. As shown, each of the first and second adapter segments 362,364 can comprise a one of the nozzle connectors 310 extending from the corresponding second adapter segment end 368, away from the inner housing 340. In the present aspect, the nozzle connectors 310 can be oriented on substantially opposite circumferential sides of the adapter ring 370. In some aspects, as shown, each of the nozzle connectors 310 can generally define an L-shape, wherein a leg 312 of the nozzle connector 310 is coupled at a proximal end 314 thereof to the second adapter ring end 378 and extends substantially axially therefrom, and an arm 318 of the nozzle connector 310 extends from a distal end 316 of the leg 312 and extends substantially radially outward therefrom. As such, the arm 318 of the nozzle connector 310 can be oriented about perpendicular to the leg 312 of the nozzle connector 310. According to example aspects, one or both of the first and second adapter segments 362,364 can further define the ramped surface 403 extending from of the inner adapter segment surface 478 at or near the second adapter segment end 368. In example aspects, a height of each of the ramped surfaces 403 can increase along its length.

In example aspects, each of the nozzle connectors 310 can be configured to rotatably engage the U.S. Storz connector 141 (shown in FIG. 1A-1B) of the nozzle 140 a. For example, in some aspects, each of the nozzle connectors 310 can be inserted into the insertion region 146 (shown in FIG. 1B) of a corresponding one of the arcuate slots 145 a,b (shown in FIG. 1B) of the U.S. Storz connector 141. The nozzle cap assembly 130 can then be rotated in a first direction (e.g., clockwise) relative to the nozzle 140 a to rotate each of the nozzle connectors 310 into the locking region 147 of the corresponding arcuate slot 145 a,b. For example, in aspects wherein the nozzle cap adapter 160 is the U.S. Storz adapter 162, and the nozzle 140 a is the U.S. Storz nozzle 142 a, the nozzle cap assembly 130 can be rotated a quarter turn relative to the U.S. Storz nozzle 142 a to engage the U.S. Storz adapter 162 therewith and to secure the nozzle cap assembly 130 thereto. As described above, the width of each locking region 147 can be lesser than the width of the corresponding insertion region 146. As such, when the nozzle connectors 310 are rotated into the corresponding locking regions 147, the arm 318 of each nozzle connector can engage the outer ring 143 of the U.S. Storz connector 141 to prohibit movement and/or removal of the nozzle cap assembly 130 in the axial direction. According to example aspects, the latch 380 can be configured to catch on one of the first and second connector arms 148 a,b to prohibit rotation movement and/or removal of the nozzle cap assembly 130 in a reverse direction (e.g., counter-clockwise), as described in further detail below with respect to FIG. 4B. Moreover, each of the connector arms 148 a,b of the U.S. Storz connector 141 can be configured to engage a corresponding one of the ramped surfaces 403 as the nozzle cap assembly 130 is rotated. In example aspects, as described above, the height of each of the ramped surfaces 403 can increase along its length. The rotation of the nozzle cap assembly 130 can move the connector arms 148 a,b in the direction of the increasing height of the ramped surfaces 403, and as such, the ramped surfaces 403 can increasingly engage the connector arms 148 a,b to tighten the nozzle cap assembly 130 onto the U.S. Storz connector 141.

FIG. 4A illustrates an exploded view of the nozzle cap adapter 160 and the inner housing 340. As shown, the inner housing 340 can define the primary mounting legs 442 extending away from the first housing body end 344 of the housing body 342 in a substantially axial direction. The inner housing 340 can further define the outer flange 346 and inner flange 348 extending away from the second housing body end 345 of the housing body 342 in a substantially axial direction, and the gasket groove 460 can be defined between the outer and inner flanges 346,348. The annular gasket 350 is provided and can be received within the gasket groove 460 when assembled with the inner housing 340. In example aspects, one or more arcuate recesses 446 formed about a circumference of the outer flange 346 at a proximal flange end 445 of the outer flange 346, adjacent to the second housing body end 345. The arcuate recesses 446 can extend generally radially inward from an outer flange surface 448 of the outer flange 346, as shown, and a non-recessed portion 452 of the outer flange 346. As shown, example aspects of the outer flange 346 can further define a semi-cylindrical recess 454 formed in the outer flange surface 448 thereof. In the present aspect, the semi-cylindrical recess 454 can extend substantially along a length of the outer flange 346, from the proximal flange end 445 thereof to a distal flange end 447 thereof.

Each of the first and second adapter segments 362,364 can be substantially semicircular in shape and can define a first adapter segment circumferential end 466 and a second adapter segment circumferential end 468. Each of the first and second adapter segments 362,364 can further define an outer adapter segment surface 476 and an inner adapter segment surface 478. In the assembled configuration, the first adapter segment circumferential ends 466 of the corresponding first and second adapter segments 362,364 can be joined together and the second adapter segment circumferential ends 468 of the corresponding first and second adapter segments 362,364 can be joined together to couple the first adapter segment 362 to the second adapter segment 364. Coupling the first and second adapter segments 362,364 together can define the adapter ring 370 (shown in FIG. 3). In the present aspect, each of the first and second adapter segments 362,364 can define a first fastener block 480 at the corresponding first adapter segment circumferential end 466 thereof. Each of the first and second adapter segments 362,364 can further define a second fastener block 482 at the corresponding second adapter segment circumferential end 468 thereof. Each of the first and second fastener blocks 480,482 can extend outward from the outer adapter segment surface 476 of the corresponding first and second adapter segments 362,364. As shown, an adapter segment fastener hole 484 can be formed through each of the first and second fastener blocks 480,482. A first one of the adapter segment fasteners 365 can engage the adapter segment fastener holes 484 of the pair of first fastener blocks 480 to couple the first adapter segment circumferential ends 466 to one another, and a second one of the adapter segment fasteners 365 can engage the adapter segment fastener holes 484 of the pair of second fastener blocks 482 to couple the second adapter segment circumferential ends 468 to one another. In example aspects, each of the adapter segment fasteners 365 can define threading configured to engage mating threading formed in the corresponding adapter segment fastener holes 484. The coupling of the first adapter segment 362 to the second adapter segment 364 by the adapter segment fasteners 365 is shown and described in further detail below with respect to FIG. 4C.

One or both of the first and second adapter segments 362,364 can define one or more arcuate ribs 402 projecting generally radially inward from the corresponding inner adapter segment surface 478 and extending at least partially along a circumference of the inner adapter segment surface 478 adjacent to the first adapter segment end 366. In some aspects, one or both of the first and second adapter segments 362,364 can further define one or more substantially semi-cylindrical ribs 404 projecting generally radially inward from the corresponding inner adapter segment surface 478 and defining a substantially semi-circular cross section. In some aspects, the semi-cylindrical rib 404 can define a rib fastener hole 406 therethrough, as shown, as will be described in further detail below. Referring to the second adapter segment 364, in the present aspect, the semi-cylindrical rib 404 can be formed adjacent to the first adapter segment end 366 and can be oriented between a pair of the arcuate ribs 402.

To secure the first and second adapter segments 362,364 to the inner housing 340, each of the first and second adapter segments 362,364 can be clamped around the outer flange 346 of the inner housing 340, and each of the arcuate ribs 402 can be configured to engage the arcuate recesses 446 formed in the outer flange 346 to prevent axial movement of the first and second adapter segments 362,364 relative to the inner housing 340. For example, axial movement can be prevented by the interference of the non-recessed portion 452 of the outer flange 346 with the arcuate ribs 402. Furthermore, the semi-cylindrical rib(s) 404 can engage the corresponding semi-cylindrical recess(es) 454 formed in the outer flange 346 to prevent rotational movement of the first and/or second adapter segments 362,364 relative to the inner housing 340. The adapter segment fasteners 365 can then couple the first adapter segment 362 to the second adapter segment 364 to define the adapter ring 370 and to prevent removal of the adapter ring 370 from the inner housing 340.

As shown, the latch 380 can be a substantially L-shaped latch 380. In other aspects, the latch 380 can define any other suitable shape. The latch 380 can define a key fastener hole 490 extending therethrough. According to example aspects, the latch 380 can be configured to nest in a latch cutout 410 formed in the first adapter segment 362. In the present aspect, the latch cutout 410 can be substantially L-shaped to generally match the L-shape of the latch 380. Furthermore, example aspects of the latch cutout 410 can be formed at the first adapter segment end 366 and can extend from the outer adapter segment surface 476 to the inner adapter segment surface 478. In other aspects, the latch cutout 410 can be differently configured. In the present aspect, the first adapter segment 362 and second adapter segment 364 can be substantially the same; for example, in some aspects, the first and second adapter segments 362,364 may be formed from the same mold or an identical mold for ease of manufacturing. As such, in the present aspect, the second adapter segment 364 can also define the latch cutout 410, but the latch cutout 410 of the second adapter segment 364 can be superfluous. In other aspects, the first and second adapter segments 362,364 can differ in configuration.

The inner housing 340 can define an inner housing cutout 415 defined by a boundary 418. In example aspects, the inner housing cutout 415 can be aligned with the latch cutout 410 of the first adapter segment 362 and can be configured to receive at least a portion of the latch 380. Example aspects of the inner housing cutout 415 can extend radially inward from a peripheral edge 416 of the housing body 342, and in the present aspect, can extend from the first housing body end 344 to the second housing body end 345. In some aspects, as shown, the inner housing cutout 415 can also extend radially inward from the outer flange surface 448 of the outer flange 346 and can span the length of the outer flange 346 from the proximal flange end 445 to the distal flange end 447. As such, the inner housing cutout 415 can span a full length of the inner housing 340, from the first housing body end 344 to the distal flange end 447. In other aspects, the inner housing cutout 415 may not span the full length of the inner housing 340 and/or may not extend into the outer flange 346.

According to example aspects, the key fastener hole 490 of the latch 380 can be aligned with the rib fastener hole 406 of the semi-cylindrical rib 404 located on the first adapter segment 362. (In the present view, only the semi-cylindrical rib 404 of the second adapter segment 364 is visible.) In this configuration, the latch 380 can be received within the latch cutout 410 of the first adapter segment 362. To couple the latch 380 to the first adapter segment 362, the latch fastener 382 can extend through each of the key fastener hole 490 and the rib fastener hole 406. In the present aspect, as shown, the latch fastener 382 can define an un-threaded portion 492 configured to extend through the key fastener hole 490 and a threaded portion 494 configured to thread with mating threading (not shown) formed in the rib fastener hole 406. As such, the latch fastener 382 can be inserted through the key fastener hole 490, and then rotated to advance the engagement of the threaded portion 494 with the rib fastener hole 406, tightening the latch fastener 382 into the first adapter segment 362.

When the nozzle cap adapter 160 is assembled to the inner housing 340, the latch 380, or portions thereof, can be received within the inner housing cutout 415, as illustrated in FIG. 3. In example aspects, the latch 380 can be configured to engage the nozzle 140 a (shown in FIG. 1A) when the nozzle cap assembly 130 (shown in FIG. 1A) is mounted thereto. For example, in a particular aspect, the spring-loaded latch 380 can be configured to slip over and catch on one of the connector arms 148 a,b of the nozzle 140 a to aid in securing the nozzle cap assembly 130 thereto. To remove the nozzle cap assembly 130 from the nozzle 140 a, a user can push the latch 380 in to disengage the latch 380 from the first or second connector arms 148 a,b, as described in further detail below, allowing for removal of the nozzle cap assembly 130.

FIG. 4B illustrates the latch 380 in further detail. As shown, the latch 380 can be received within the latch cutout 410 and can be pivotably mounted to the first adapter segment 362 by the latch fastener 382. Example aspects of the latch 380 can be spring-biased to an engaged configuration, as shown, but can be rotatable to a disengaged configuration upon application of a sufficient force, as described in additional detail below. As shown, in the present aspect, the latch 380 can define a latch leg 482 defining a first latch leg end 481 and a second latch leg end 483. The latch 380 can further define a latch arm 486 extending from the latch leg 482 proximate to the first latch leg end 481 and oriented substantially perpendicular to the latch leg 482. According to some example aspects, the latch arm 486 may define a sloped latch surface 487, as shown. In the engaged configuration, the spring-biased latch 380 can be oriented such that the latch arm 486 can be rotated generally inward toward the cap axis 201 (shown in FIG. 3), while the second latch leg end 483 can rotated generally outward. In the disengaged configuration, a force (e.g., a manual force or a force supplied by a tool) can be applied to the second latch leg end 483 of the latch leg 482 to rotate the second latch leg end 483 inward and to rotate the latch arm 486 outward.

In example aspects, as described above, the nozzle connectors 310 of the nozzle cap adapter 160 (shown in FIG. 1A) can engage the insertion region 146 (shown in FIG. 1B) of a corresponding one of the arcuate slots 145 a,b (shown in FIG. 1B) of the U.S. Storz connector 141 (shown in FIGS. 1A-1B), and the nozzle connectors 310 can be rotated in the first direction (e.g., clockwise) into the locking region 147 (shown in FIG. 1B) of the corresponding arcuate slot 145 a,b. As the nozzle cap adapter 160 is rotated, the latch 380 can also be rotated towards a corresponding one of the connector arms 148 a or 148 b. When the latch 380 passes the corresponding connector arm 148 a,b, the latch arm 486 of the spring-biased latch 380 can be biased inward (i.e., the latch arm 486 can pivot inward about the latch fastener 382 towards the cap axis 201), such that the latch 380 can catch against the corresponding connector arm 148 a,b. The engagement of the latch arm 486 with the corresponding connector arm 148 a,b can prohibit the nozzle cap adapter 160 from being rotated in the reverse direction (e.g., counter-clockwise), and thus, can prohibit removal of the nozzle cap assembly 130 (shown in FIG. 1A) from the fire hydrant 110 (shown in FIG. 1A). However, when a suitable force is applied to the second latch leg end 483 of the latch leg 482, the latch arm 486 can be pivoted outward, such that the latch 380 can clear the corresponding connector arm 148 a,b, and the nozzle cap assembly 130 can be rotated in the reverse direction for removal from the fire hydrant 110.

FIG. 4C illustrates a cross-sectional detail view of the first adapter segment circumferential ends 466 of the first and second adapter segments 362,364 joined together by the corresponding adapter segment fastener 365. As shown, in example aspects, the adapter segment fastener 365 can define a fastener head 367 and a fastener tail 369 extending from the fastener head 367. The fastener tail 369 can define fastener threading 371 in some aspects. In the present aspect, the fastener tail 369 can be inserted through the adapter segment fastener hole 484 of the first fastener block 480 of the first adapter segment 362, which can be an unthreaded hole in some aspects. The adapter segment fastener 365 can then thread into the adapter segment fastener hole 484 of the second adapter segment 364, which can be a threaded hole in the present aspect, to secure the first adapter segment 362 to the second adapter segment 364 at the first adapter segment circumferential ends 466 thereof. According to example aspects, the second adapter segment circumferential ends 468 can be secured together in substantially the same manner.

FIG. 5 illustrates the nozzle cap assembly 130 comprising the nozzle cap 150 and the nozzle cap adapter 160, in accordance with another aspect of the present disclosure. As shown, the nozzle cap 150 can comprise the cap cover 280 and the cap body 210, and the cap body 210 can comprise the outer housing 230 and the inner housing 340. The nozzle cap adapter 160 can be coupled to the inner housing 340 of the nozzle cap 150 to allow the nozzle cap 150 to be mounted to the nozzle 140 a (shown in FIG. 1A) of the fire hydrant 110 (shown in FIG. 1A). For example, the nozzle cap adapter 160 can again be the U.S. Storz adapter 162, which can be configured to mount the nozzle cap 150 to the U.S. Storz nozzle 142 a (shown in FIG. 1A). The nozzle cap adapter 160 can comprise the adapter ring 370, latch 380, and gasket 350, as shown. Furthermore, as shown in the present aspect, the inner housing 340 may not comprise the outer and inner flanges 346,348. Rather, the nozzle cap adapter 160 can comprise a gasket housing 560, and the gasket housing 560 can comprise the outer and inner flanges 346,348. The outer and inner flanges 346,348 of the gasket housing 560 can define the gasket groove 460 (shown in FIG. 6) therebetween, which can be configured to receive the gasket 350 therein. The gasket housing 560 can be coupled to one or both of the inner housing 340 and adapter ring 370, as described in further detail below with respect to FIG. 6. In some aspects, as shown, the inner housing 340 also may not comprise the inner housing cutout 415 (shown in FIG. 4A).

FIG. 6 illustrates an exploded view of the inner housing 340 of FIG. 5 and the nozzle cap adapter 160 of FIG. 5. As shown, the inner housing 340 comprises the housing body 342 defining the first housing body end 344 and second housing body end 345. The primary mounting legs 442 can extend from the first housing body end 344 for mounting the inner housing 340 to the outer housing 230 (shown in FIG. 2). In some aspects, the inner housing 340 can further comprising a clearance hole 642, and the adapter ring 370 can define a first adapter ring key hole 672. The clearance hole 642 and the first adapter ring key hole 672 can be substantially aligned, as described in further detail below. Moreover, in the present aspect, the inner housing 340 can define one or more secondary mounting legs 644 extending from the second housing body end 345 generally in the axial direction. The secondary mounting legs 644 can be oriented radially inward from the primary mounting legs 442 in some aspects. As shown, each of the secondary mounting legs 644 can define a secondary mounting leg hole 646 configured to receive a gasket housing fastener (not shown) therethrough. For example and without limitation, the gasket housing fastener may be a screw or a bolt in some aspects. The gasket housing fastener(s) can be configured to engage the gasket housing 560, as described in further detail below, to couple the gasket housing 560 to the inner housing 340.

In some example aspects, as shown, the adapter ring 370 can be monolithically formed and may not comprise the first and second adapter segments 362,364 (shown in FIG. 3). The adapter ring 370 of the present aspect can be configured differently from the adapter ring 370 shown in the aspect of FIGS. 3-4C. However, similar to the aspect of FIGS. 3-4C, the present adapter ring 370 can define the first adapter ring end 376 and the second adapter ring end 378. The adapter ring 370 can further generally define an outer adapter ring surface 676 and an inner adapter ring surface 678. In the present aspect, one or more adapter ring reinforcement ribs 680 can extend from and be spaced about a circumference of the outer adapter ring surface 676. Furthermore, as shown, an annular adapter ring flange 682 can extend generally radially inward from the inner adapter ring surface 678, and can define a flange upper surface 684 and a flange lower surface (not shown). The nozzle connectors 310 can extend from the second adapter ring end 378 and can be oriented on substantially opposite sides of the adapter ring 370. The nozzle connectors 310 of the present aspect can define the L-shape, comprising the leg 312 and arm 318 as described above, and can be configured to engage the nozzle 140 a (shown in FIG. 1A) to secure the nozzle cap assembly 130 (shown in FIG. 1A) to the nozzle 140 a.

Moreover, the adapter ring 370 can define a latch alcove 686 formed therein for receiving the latch 380, similar to the latch cutout 410 (shown in FIG. 4A) described above. As shown, the latch 380 can be substantially similar to the latch 380 described above with respect to FIGS. 3-4A. For example, the latch 380 can be substantially L-shaped and can define the key fastener hole 490 extending therethrough. In the present aspect, the latch alcove 686 can be partially bound by a latch shelf 688 extending from the outer adapter ring surface 676, proximate to the first adapter ring end 376 thereof. The latch shelf 688 can define the first adapter ring key hole 672 formed therethrough. In some aspects, the adapter ring 370 can define a second adapter ring key hole (not shown) formed therein, wherein the second adapter ring key hole can be aligned with the first adapter ring key hole 672 and oriented at an opposing side of the latch alcove 686. As such, in example aspects, the latch fastener 382 (shown in FIG. 3) can extend through the first adapter ring key hole 672 and key fastener hole 490, and into the second adapter ring key hole, to couple the latch 380 to the adapter ring 370. In some aspects, when the nozzle cap adapter 160 is mounted to the inner housing 340, a portion of the latch fastener 382 may extend into the clearance hole 642. However, in other aspects, the latch fastener 382 may not extend into the clearance hole 642.

Example aspects of the gasket housing 560 can define a first gasket housing end 662 and a second gasket housing end 664. The outer and inner flanges 346,348 can be formed at the second gasket housing end 664, as shown. Furthermore, an annular gasket housing shoulder 666 can extend generally radially outward from an outer gasket housing surface 668 at a location between the first gasket housing end 662 and the outer and inner flanges 346,348. In some aspects, such as the present aspect, the gasket housing 560 may not be directly coupled to the adapter ring 370. However, in other aspects, the gasket housing 560 may be directly coupled to the adapter ring 370. For example, in one aspect, mechanical fasteners (e.g., screws, nuts and bolts, etc.) may be provided for coupling the gasket housing 560 to the adapter ring 370. In another example aspect, the gasket housing 560 may define external threading configured to thread into internal threading the adapter ring 370 (or vice versa) to couple the gasket housing 560 to the adapter ring 370. To mount the nozzle cap adapter 160 to the inner housing 340, the first adapter ring end 376 of the adapter ring 370 can be positioned to abut the second housing body end 345 of the housing body 342. The gasket housing 560 can then be inserted into the interior void 372 of the adapter ring 370. The annular gasket housing shoulder 666 can engage the flange upper surface 684 of the annular adapter ring flange 682 to retain the adapter ring 370 between the gasket housing 560 and the inner housing 340. Each of the secondary mounting legs 644 can extend into the interior void 372 of the adapter ring 370, and the secondary mounting leg hole 646 of each secondary mounting leg 644 can be aligned with a gasket housing hole (not shown) formed at the first gasket housing end 662. The gasket housing fastener (not shown) can be configured to extend through each of secondary mounting leg 644 holes 646 and into a corresponding one of the gasket housing holes to couple the gasket housing 560, and thus couple the nozzle cap adapter 160, to the inner housing 340.

FIG. 7 illustrates the nozzle cap assembly 130 comprising the nozzle cap 150 and the nozzle cap adapter 160, in accordance with another aspect of the present disclosure. As shown, the nozzle cap 150 can comprise the cap cover 280 and the cap body 210, and the cap body 210 can comprise the outer housing 230 and the inner housing 340. The nozzle cap adapter 160, such as the U.S. Storz adapter 162, can be coupled to the inner housing 340 of the nozzle cap 150 to allow the nozzle cap 150 to be mounted to the nozzle 140 a, such as the U.S. Storz nozzle 142 a (both 140 a and 142 a shown in FIG. 1A), of the fire hydrant 110 (shown in FIG. 1A). The nozzle cap adapter 160 of the present aspect can be similar to the nozzle cap adapter 160 of FIGS. 5-6. For example, the nozzle cap adapter 160 can comprise the adapter ring 370 and the gasket housing 560. Furthermore, the latch 380 can be received in the latch cutout 410 of the adapter ring 370, and the gasket 350 can be received in the gasket groove 460 (shown in FIG. 8) of the gasket housing 560. However, in the present aspect, the inner housing 340 and portions of the adapter ring 370 can be configured differently from the aspect of FIGS. 5-6, as shown and described in further detail below with respect to FIG. 8.

FIG. 8 illustrates an exploded an exploded view of the inner housing 340 of FIG. 7 and the nozzle cap adapter 160 of FIG. 7. The nozzle cap adapter 160 can be similar to the nozzle cap adapter 160 of FIGS. 5-6, as described above. However, in the present aspect, the adapter ring 370 can comprise the latch cutout 410 instead of the latch alcove 686 (shown in FIG. 6). Furthermore, the inner housing 340 can define the housing body 342, and the housing body 342 can define the first housing body end 344 and the second housing body end 345. The primary mounting legs 442 can extend from the first housing body end 344 for engaging the mounting recesses 236 (shown in FIG. 2) of the outer housing 230 (shown in FIG. 2). A housing body opening 844 can be formed substantially through a center of the housing body 342, such that the housing body opening 844 is substantially concentric to the cap axis 201, and can extend from the first housing body end 344 to the second housing body end 345. In the present aspect, a first locking ring 810 can be provided for coupling the adapter ring 370 to the inner housing 340. As shown, the first locking ring 810 can abut an inner housing shoulder 848 formed at a boundary 846 of the housing body opening 844, preventing the first locking ring 810 from advancing through the housing body opening 844 in a direction towards the second housing body end 345. The first adapter ring end 376 can pass through the housing body opening 844, and the first locking ring 810 can be configured to engage an annular adapter ring slot 872 formed in the outer adapter ring surface 676 to couple the adapter ring 370 to the inner housing 340. Furthermore, in the present aspect, a second locking ring 815 can be provided for coupling the gasket housing 560 to the adapter ring 370. The second locking ring 815 can abut the flange lower surface of the annular adapter ring flange 682 to prevent the second locking ring 815 from advancing through the interior void 372 of the adapter ring 370 in a direction towards the nozzle connectors 310. The gasket housing 560 can be inserted into the interior void 372 through the second adapter ring end 378, and the second locking ring 815 can be configured to engage an annular gasket housing slot 862 formed in the outer gasket housing surface 668 of the gasket housing 560 to couple the gasket housing 560 to the adapter ring 370.

FIG. 9 illustrates the nozzle cap assembly 130 comprising the nozzle cap 150 and the nozzle cap adapter 160, in accordance with another aspect of the present disclosure. Again, the nozzle cap 150 can comprise the cap cover 280 and the cap body 210, and the cap body 210 can comprise the outer housing 230 and the inner housing 340. The nozzle cap adapter 160 can be coupled to the inner housing 340 of the nozzle cap 150 to allow the nozzle cap 150 to be mounted to the nozzle 140 a (shown in FIG. 1A). The nozzle cap adapter 160 of the present aspect can be similar to the nozzle cap adapters 160 of FIGS. 5-6 and FIGS. 7-8. For example, the nozzle cap adapter 160 can comprise the adapter ring 370 and the gasket housing 560. Furthermore, the latch 380 can be received in the latch cutout 410 of the adapter ring 370, and the gasket 350 can be received in the gasket groove 460 (shown in FIG. 10) of the gasket housing 560. However, in the present aspect, the inner housing 340 and portions of the adapter ring 370 can be configured differently from the aspect of FIG. 5-6, as shown and described in further detail below with respect to FIG. 10.

FIG. 10 illustrates the inner housing 340 of FIG. 9 and the nozzle cap adapter 160 of

FIG. 9. The gasket housing 560 can be substantially the same as the gasket housing 560 of FIGS. 7-9, and the second locking ring 815 can couple the gasket housing 560 to the adapter ring 370 in the same manner. However, the present aspect does not comprise the first locking ring 810 (shown in FIG. 8). Rather, the inner housing 340 can define internal threading 1042 formed at the boundary 846 of the housing body opening 844. Furthermore, the adapter ring 370 can define external threading 1072 formed on the outer adapter ring surface 676 proximate to the first adapter ring end 376. The external threading 1072 of the adapter ring 370 can thread into the internal threading 1042 of the inner housing 340 to couple the nozzle cap adapter 160 to the inner housing 340. In some example aspects, as shown, the inner housing 340 can define a housing body shoulder 1044 extending radially inward from the boundary 846 of the housing body opening 844 at the first housing body end 344 thereof. The housing body shoulder 1044 can serve as a stop by engaging the first adapter ring end 376 of the adapter ring 370 when the adapter ring 370 is appropriately tightened onto the inner housing 340.
